Exhaust Help Needed

[GTR Cook]

I am after changing my exhaust on my 172 Cup, i think its a standard exhaust that the baffles have gone walkies from. It sounds like a bag of spanners at idle and drones on the motorway, so it needs to go.

I was looking at the KTEC stealth or maybe going for a standard exhaust from Renault.

The question is, which is the better option?

I am looking to do trackdays so it needs to be fairly quiet and i would like to do Bedford in particular.

Will something like a KTEC stealth be quiet enough for Bedford?

Id go for a stainless steel one mate either a ktec or a yozza if you want to spend more both will be fine for trackdays.

ktec = drone
I would go yozza or supersprint stealth

Thanks for the advice, will look into the Yozza.

Do you know what DB level the Yozza produces with a cat? Or if anyone has run this exhaust at Bedford that would be great.

Plenty of people have run a Yozza at Bedford, no where near the noise limit. If you want it quiet, buy a Yozza stealth, if you want a bit more noise, get the race stealth. Both will pass noise testing easily with a cat in.

I think a decatted Yozza race is 96db iirc.... and that's the loudest system they make.

I had the K-tec stealth and it was horribly drony inside the car, I now have a Yozza race with the cat still in and it's a LOT better.

jack_kemp, appreciate the info, has definately made my mind up for a Yozza system.

Hope to be out on track soon!

These are also very very nice systems, heavy though, which is why I went for the Yozza.
